Question

Calculate the % trophic level efficiency of the wolves if the productivity of the cats eaten by the wolves is 96000 and the productivity of the wolves is 9000.

Answer 1

All trophic levels have different efficiencies, thus different energy levels. The first trophic level is the one that produces all of the energy, and that energy travels thought he trophic levels above, but from one to another trophic level the energy is lost, and it is usually around 10% that is transferred. In this case, in order to see what is the efficiency of the the energy tarnsfer we simply need to divide the trophic efficiency of the cats, with the trophic efficiency of the wolves:

96,000 / 9,000 = 10.67%

So we have a trophic efficiency of the wolves of 10.67%.
